UNITED STATn-s PATENT @Erica JAMES COLLINS, OF ORAVFORDSVILLE, INDIANA.

TWOf-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 281,023, dated July 10, 1883.

Application filed September 30, 1882. (No model.)

To all whom it may concern.-

Be it known that I, JAMns CoLLiNs, a citizen of the United States, residing at Crawfordsville, in the county of Montgomery and State of Indiana, have invented a new and valuable Improvement in Road-Carts; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and ligures of reference marked thereon.

Figure l of the drawings is a vertical sectional view of my road-cart, and Fig. 2 is a top or plan view of the same.

This invention has relation to road-carts or two-wheel vehicles; and it consists inthe construction and novel arrangement of the spring side bar secured to the shaft, and having a rising bend near the seat which it'supports; the adjustable bearing on the shaft engaging the spring; the seatspring rigidly secured to the seat or seat-frame, and having its movable end engaging the shaft-bearing; the coil seat-spring havingl an extension from the box or frame of the seat engaging the shaft-bearing; and the stay-spring extending from the drop or footrest of the body back to the axle, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the axle; B, the shafts; C, the seat or body, and D the drop or foot-rest.

E represents the side bars," which are firmly secured to the shafts, extending back parallel therewith to point-s near the front of the seat, and there formed with a rising double bend, a., from the upper portion of which each side bar extends horizont-ally to the rear, the raised portion b serving as a bearing for the seat or body. This side bar is designed to give the seat sufficient height without forming an obstruction at the side or entrance.

F indicates a clip or bearing, which is bored or slotted to engage the seat-spring, and is fastened to the shaft in an adjustable manner, so that it can be moved backward or forward. By adjusting this bearing the seat-spring can be made more or less yielding, according to the weight to be supported.

G designates the seat-spring, which is rigidiy secured at its upper end to the seat or body, its lower end, c, being free or movable upon the shaft or shaft-bearing, which it engages. The upper or main portion of the seatspring is usually constructed in spiral forni, as indicated at d, the spiral being inclosed in the body or seat-frame, and the arm or lower portion, c, extending outward and downward therefrom. This spring is designed to afford a yielding support to the seat in rear, and as its arm or extension c bears on the rear portion of the shaft just upon or in front of the bend or arch e, the strain upon the shaft is reduced materially, so that it can be made light and neat in form.

H represents a Stayspring, which is attached to the drop or foot-rest frame on each side, and, extending back, is secured to the axle. These springs H are designed to hold the body in proper position, keeping it steady and preventing a twisting vibration.

Inclined spring-bars have been connected at their lower ends by bolts or clips to the shafts and extended back and over the axle to support the sulky-seat prior to my invention, and inclined seat-supporting spring-bars have been secured at and also near their lower forward ends, between the side bars of the sulkyframe, to two transverse cross-bars of said frame, and extendedY back and over a rear transversebar above the axle, and connected to the rear transverse bar by downwardly, forwardly, then upwardly and rearwardly curved springs. I nud, too, that a single thin plate or spring centrally located has been employed to connect the front of the body to the axle, but this lastconstruction permits a twisting vibration of the body, which I aim to over come. It is not intended to make claims herein for either of these constructions, as I admit that they were in use prior to my invention.

Having described this invention, what I claim, anddesire to secure by Letters Patent, is

1. The spring side bar, E, secured to the shaft in front of the body, extending back parallel therewith, and having a rising double bend, c, near the front of the seat, substantially as specified.

2. The combination, with the seat and the seat-spring G, attached thereto, of the adjustable clip or bearing E, Connected to the sha fb eat-sprlng sub tantlall my 3. The combination, with the shafts of a two-Wheel vehicle, ofthe seat spring or springs G, rigidly secured to the seat-frame or body,

and having their, arms, kc extending fomvardw mld downward to engage the snfebearigsj substantially as speoed.

4. The seat-spring G, having the spjgahupgj per portion, d, seated in the body or frame of the seat, and the arm or extension c extending downward and; :fomvard'l therefrom, gsnbffV stantially as specified.
